TERMINAL BLOCK.

Specification of Letters Patent.

Patented Apr. 11,1922.

Application fllcd February 17, 1921. Serial No. 445,795.

To all whom it may concern:

Be it known that I, THOMAS L. LEE, a citizen of the United States, residing at Rochester, in the county of Monroe and State of New York, have invented certain new and useful Improvements in Terminal Blocks; and I do hereby declare the following to be a full, clear, and exact description of the inveution, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to means for mounting and insulating the terminals and the fuse used in connection with a dynamo-electric machine.

In connection with the dynamo used on a motor-vehicle, it is common to use a fuse, which is usually mounted on the frame of the machine at some convenient point. The object of the present invention is to produce a simple, compact and convenient arrangement wherein the fuse-mounting and the insulating supports for the terminals of the dynamo are combined in a unitary member, and the parts are so brought together that they are readily accessible and conveniently located for connection with the internal conductors of the dynamo.

To the foregoing end the invention consists in the terminal-block hereinafter described, as it is defined in the annexed claims.

In the accompanying drawings Fig. 1 is a plan-view of a terminal-block embodying the present invention, and Fig. 2 is a section on the line 22 in Fig. 1, showing also a part of the frame of the machine on which the block is mounted. y

The invention is illustrated as embodied in a terminal-block comprising an integral body of insulating material, preferably moulded of bakelite or other plastic sub stance. This body comprises a base-portion 5 which is suitably shaped, on its inner or lower surface, to rest on the frame of the dynamo.

Rising from the middle part of the outer face ofthe base-portion 5 are two side-walls 6 connected, at one end, by an end-wall 7. These three walls provide a fuse-receptacle, which is open at one end to facilitate the removal of the fuse.

From the inner face of the base-portion depend two 0 lindrical projections 8, in which are fixe or embedded the terminals 20 of the dynamo. These terminals are in the form of tubes with threaded perforations, and, in combination with screws 9 and 10 each terminal constitutes two bindingposts accessible, respectively, from the out-' connected, by wires 16, to the windings or I other parts of the dynamo within the frame 21, While one of the fuse-clips is connected, by a strap 18, with one of the terminals. The connections to the other fuse-clip are not shown. The outer binding-posts serve for the attachment of wires 17 .by which the dynamo is connected with other apparatus. v I

In addition to the walls 6 and 7 already described, the terminal-block is provided with walls 19 projecting laterally from the walls 6 near the open end of the fuse-receptacle' These walls 19 not only provide enclosures for the binding-posts, thus improving the resistance of these parts, but they also brace the walls 6 at points where they would otherwise be weak.

The invention is not limited to the details of construction of the illustrated embodiment, but. may be embodied in various other forms within the scope of the following claims.

The invention claimed is: v

1. A terminal-block, for a dynamo-electric machine, comprising: an integral body of insulating-material, consisting of a base-portion formed to'seat upon the frame of the machine, and walls rising from the baseportion and forming a fuse-receptacle; fuseclips mounted in the fuse-receptacle; binding-posts on the outerface of the base-portion at the sides of the fuse-receptacle; and binding-posts on the inner face of the baseportion and connected with the fuse-clips and the outer binding-posts, respectively.

2. In combination with the-frame of a dynamo-electric machine: an integral body of insulating-material consisting of a base- 110 portion formed to seat on the outer surface of the frame, Walls rising from the outer face of the base-portion and forming a fusereceptacle, and inward pro ect1ons extending through openings in the dynamo-frame; fuse-clips in the fuse-receptacle; bindingposts on the outer face of the base-member, at the sides of the fuse-receptacle; and terminal-members connected With the bindingposts and extending, throngh said inward projections of the insulating material and accessible at the interior of the dynamoframe.

3. A terminal-block, for a dynamo-electric machine, comprising: an integral body of insulating-material, consisting of a base-portion formed to seat on the frame of the machine, two side-Walls and an end-yvall rising from the base-portion and providing a fusereceptacle open at one vend, and a pair of laterally-extending walls pro ecting from each side-Wall of the fuse-receptacle at the open end of the fuse-receptacle; a bindingpost mounted between each of said pairs of laterally-extending walls; and fuse-clips mounted in the fuse-receptacle.

4. A terminal-block, for a dynamo-electric machine, comprising: an integral body of insulating-material, consisting of a base-portion formed to seat on the frame of the machine, two side-walls and an end Wall rising from the outer face of the base-portion and providing a fuse-receptacle open at one end, a Wall extending laterally from each side-Wall near the open end of the fusereceptacle, and projections from the inner face of the base-portion, at the sides of the fuse-receptacle; and terminal members through said projections and accessible at both faces of the base-portion.
